Moisture in POE Oil Permanently Damages HVAC Systems with Jim Bergmann

In this episode of the HVAC Know It All Podcast, host Gary McCreadie welcomes Jim Bergmann, President of measureQuick and Director of New Product Development at Redfish Instruments Inc, to discuss system cleanup after moisture contamination and compressor burnouts. Jim explains why moisture in POE oil cannot be fully removed with evacuation and highlights the importance of using filter dryers and proper procedures. The conversation covers real-world scenarios such as water entering a system and the steps needed to reduce damage and extend equipment life. Gary and Jim also talk about evacuation best practices, decay testing, and how poor installation habits can lead to long-term system failure.

In this conversation, Jim explains how moisture affects refrigeration systems and why it cannot be fully removed from POE oil using evacuation alone. He discusses how technicians should rely on filter dryers, oil changes, and proper cleanup methods to reduce contamination. Jim and Gary talk about real situations like water entering a system and compressor burnouts, and how these issues damage equipment and shorten its life. They also explain the importance of good installation practices, proper evacuation, and decay testing to prevent future failures and ensure the system stays clean and dry.
